I disagree with the notion of a USSR-esque breakup of the United States. The U.S. was not merely as autocratic or economically backwards as the USSR and the more militaristic American culture will probably ensure the stiff pin-down of the C.S.A. and Canada. IIRC the U.S. Military of ATL did not follow the rules of war and committed reprisal killings (10 civilians for 1 dead U.S. soldier killed or something like that), so I have a feeling that the ex-Confederates and Canadians would lose hope in becoming independent again in lieu of their people being murdered for the actions of others.
I could see the Canadians seeing themselves as Americans around the 50s, while the Confederates would become Americanized around the late 60s or 70s.
A more militaristic US culture is going to harm integration of Canadians and Confederates (and definitely of the Mormons). Reprisal attacks were commonplace in TL-191 US, that's true, but that's only going to breed resentment. I agree with rvbomally, reprisal killings will lead to non-violent resistance (and Craigo in the Filling the Gaps thread had Lester Pearson start a nonviolence movement borrowing elements from Mahatma Gandhi and Henry David Thoreau, quoted below)
Of particular interest is the growing peace movement under Lester Pearson, an academic in Ontario. Pearson, who fought in the Great War and the First Rebellion, now draws on the ideas of the American Thoreau and the Indian Gandhi, and advocates "peaceful struggle." Whether this new tactic will have any effect against a military occupation is yet to be seen.
Justifying the occupation is going to get harder and harder, especially if the US government continually paints them as irredeemably evil. How do you integrate conquered peoples into your own country and paint them as evil? How do you integrate people your parents or grandparents remember fighting? There's going to be a lot of scars and I don't think the American people will be able to swallow integrating the Canadians and ex-Confederates; the Canadians fought three wars against the US, launched two large-scale rebellions against the military occupation, and now have an independence movement homegrown dedicated to freeing Canada from American occupation. The South is going to be an even bigger can of worms: they fought three wars against the US, killed millions of their own black citizens, and now have Southern resistance to the US occupation and neo-Freedomite terror.
The best you can hope for is a sufficiently Americanized population, but the rise of independence movements and neo-nationalism is going to make things infinitely more difficult, especially selling the idea that Canadians in Alberta or Southerners in Mississippi can be represented in Congress. We're talking the US integrating their Canadian and Southern occupied territories by the 1960s and there's still going to be a vast number of Americans who remember heading north to crack Canadian skulls, or remember liberating death camps in the South. And you're telling them that Canadians and Southerners, growing up under American occupation, are ready to be integrated into the US?
I wonder if anyone else in this thread has read Does Conquest Pay?
It's been ages since I read it, but I've linked it here if anyone else wants to read it.
Why not? It's not a planned economy run by Joseph Stalin.
Maintaining a decades-long occupation isn't going to help them (they've already been occupying Canada since 1917). The US is going to want to focus on rebuilding everything theirs that was damaged or destroyed in the SGW, then helping their Special Relationship buddy Ireland, and then Canada and the ex-CSA. Hundreds of millions of dollars to rebuild, infrastructure damaged or destroyed, the economy in at least a dozen states is going to take years to revive. Not to mention the Southern economy is practically non-existent, the Canadians have damaged the economy up north with a three-year rebellion, and the arrival of a tripolar cold war setting between Americans, Germans and Japanese? It doesn't look good economically for the United States.
